In this video I’ll show you exactly how I set up voice keying in N1MM so the computer handles the repetitive contest exchanges for me.
We’ll cover:
• Recording your own WAV files
• Where to store them inside the N1MM folder structure
• Setting up the function key macros (F1, F2, F3, etc.)
• Using concatenated WAV files to eliminate audio clicks between messages
• Sharing operator-specific callsigns and messages
I’ve also included a download link (below) containing my macro layout, recording checklist and example files to help you build your own voice keyer.
Anytone AT-5000: The CB Radio You'll Want To Modify! #shorts
We thought it was one thing, but it’s another! Let’s dive into the Anytone AT-5000 CB radio and see what it’s really made of. Get ready for some radio fun!
Jeff asks for the deeper information of how choke baluns work to see if he can create a workable choke balun, for just 10 meters.

This is an introductory, practical guide to common-mode chokes (often called "ugly baluns") aimed at everyday amateur radio operators.
The explanations are deliberately simplified to help illustrate what happens when RF current flows on the outside of the coax shield, why this can happen, and how a common-mode choke helps reduce it.
For those interested in the detailed engineering, Steve Hunt G3TXQ (SK) carried out extensive measurements on common-mode chokes and his work remains one of the best practical references available. His data was invaluable when I built my own chokes – link here:
http://www.karinya.net/g3txq/chokes/
As with most things in RF engineering, antenna balance, feedline routing, nearby objects and operating frequency all influence the amount of common-mode current present. The values mentioned in this video are simply those I’ve found to work well on my own station.
How I Eliminated (almost) All The Inverter RFI In My Camper
I was finally able to get the teardrop out to the state park in an RF quiet environment to hunt down all that nasty RFI being caused by that LiTime 2000 watt inverter. Caitlin and I spent about an hour or so trying one variable at a time to see what made a difference and what did absolutely nothing. In the end, we were finally able to get the RFI down so much we went from an S9+ noise being caused by the inverter to and S0! It’s still not perfect, I have some more work to do, but I used everything I currently own to mitigate as much of the RFI as possible and boy howdy did it make a difference! If you have any ideas to help squash these final spurs every 35kHz please share them with the group.

In this video I’m building an AIOC using the AIOC solder guide, then checking whether the finished board fits properly inside the 3D printed AIOC case. The goal is simple: make the soldering process cleaner, reduce the tiny-board frustration, and see if the case, top, bottom, and guide all work together in the real world instead of just looking good on the printer bed.

👉 Slim Case: https://www.printables.com/model/713555-aioc-enclosure
👉 My Choice for Case: https://www.thingiverse.com/thing:6144997
By the end, I’ll show the full build, the fit test, and what worked or needed attention. You can buy the AIOC, have me solder the AIOC for you, and also pick up the 3D printed case and solder guide if you want the same setup without fighting the tiny pads yourself. This is part electronics build, part 3D print test, and part “does this actually fit?” bench experiment.
